Abstract: A bearing assembly is formed by coupling at least two units together in an axially abutting manner. Each unit has two connection portions on two opposite ends and a mounting portion on a largest outer periphery. The connection portions between two adjacent units form at least one set of interfaces, each set having complementary shapes contact with each other. The mounting portion is securely encased in an inner periphery of a jutting chamber located at each end of a motor housing. At least one groove and notches are formed on at least one of two abutting connection portions between the two adjacent units. The notches communicate with the groove and an axle hole. In the assembly, the groove forms at least one storage chamber to store lubricating media, and the notches form at least one set of passages communicating with the storage chamber and an axial hole.

Abstract: A heavy load bearing includes a casing and assembly having at least two units and an axial hole run-through by a shaft. Each unit has a mounting portion on the circumferential outer surface, two connection portions at two ends, an axle hole, and at least one groove indented axially from the connection portion and formed between an outer wall near the mounting portion and an inner wall near the axle hole. At least one set of multiple notches is formed annularly on a free end of the inner wall and communicating with the groove and axle hole. The casing has an axial cavity to hold the assembly. Two abutting units are coupled to form at least one storage chamber to store lubricating media. The notches of the two abutting units form at least one set of multiple fine flow passages communicating with the axial hole and storage chamber.

Abstract: A bearing includes a housing and an assembly which consists of at least two elements. Each element has an axle hole to form an axial hole of the assembly run through by a shaft. At least one element has at least one set of multiple notches formed thereon directing towards at least one of two ends thereof to communicate with the axle hole, and at least one groove with an enlarged opening formed on the wall surface of the axle hole directing towards the notches. The groove on the wall surface of the axle hole has at least one set of multiple recesses formed thereon. The housing has a through axial cavity to house the assembly. The bearing has at least one storage chamber to store lubricating media. The notches on at least one set of adjacent elements form at least one set of multiple passages communicating with the storage chamber and the axial hole.

Abstract: A hybrid lubricating module includes a housing and an assembly which consists of at least two elements and has an axial hole run through by a shaft. At least one of the elements has one set of multiple notches on one end surface communicating with an axle hole. The housing has a through axial cavity to encase the assembly. An outer wall surface of the assembly and an inner wall surface of the housing are assembled to each other to form at least one storage chamber to store lubricating media. Multiple notches on at least one adjacent element form at least one set of passages communicating with the axial hole and the at least one storage chamber.

Abstract: A miniature lubricating assembly is formed by coupling at least two units together in an axially abutting manner. Each unit has two connection portions on two opposite ends and a mounting portion on a largest outer peripheral surface. The connection portions between two adjacent units form a pair of interfaces with complementary shapes so as to couple tightly with each other. The mounting portion is securely encased in an inner wall surface of a chamber located at each end of a motor housing. At least one groove and a plurality of notches formed on at least one of the connection portions between two adjacent units. The notches communicate with the groove and an axle hole. In the assembly, the groove forms at least one storage chamber to store lubricating media, and the notches form at least one set of passages communicating with the storage chamber and an axial hole.

Abstract: A high speed bearing includes a housing and an assembly having at least two elements. Each element has an axle hole to form an axial hole of the assembly run through by a shaft. At least one element has at least one set of multiple notches formed thereon directing towards at least one of two ends thereof to communicate with the axle hole, and at least one groove with a vent formed on the wall surface of the axle hole directing towards the notches. The groove has at least one set of multiple recesses formed thereon. The housing has a through axial cavity to house the assembly. The assembly has at least one storage chamber to store lubricating media. The notches on at least one set of adjacent elements form at least one set of multiple fine flow passages communicating with the storage chamber and axial hole.

Abstract: A self-lubrication bearing structure includes a bearing, which is made from a porous material capable of absorbing and transferring a lubricating oil and which has a center axle hole for the passing of the shaft of a motor and multiple oil retaining grooves that retain a lubricating oil, and a casing surrounds the bearing around the shaft of the motor. During rotation of the shaft, the lubricating oil is caused to move out of the porous structure of the bearing to lubricate the shaft. When the rotation of the shaft is stopped, the lubricating oil flows back to the oil retaining grooves.

Abstract: A transmission shaft set includes a shaft for use in a motor for power output and an axle bush adapted to support the shaft, the shaft and the axle bush being respectively made of material of high toughness and material of high harness such that the hardness difference between the shaft and the axle bush is about Hv100˜Hv400, and the hardness of the axle bush is higher than the shaft.
